Ok, so what is happening here is a shortcoming of the xdgmime
implementation. It doesn't handle
different versions of caches in different directories very well. Here
it sees a cache it understands in
~/.local, so it decides to use the caches. But it can't understand the
cache in /usr/share since it is
a newer version, so all the mime data from /usr/share is ignored. A
better implementation would make
the cache-or-no-cache decision for each directory individually.
